6.10.1 High-Efficiency Packaged Air-Cooled

Chiller

Commissioning Process Summary

The Commissioning Process for the high-efficiency packaged air-cooled chiller EEM

includes pre-startup inspections of the installed equipment, systems, and subsystems,

and the execution of the verification and functional performance testing of the chiller,

pumps, and chiller control system. The fundamental operational and performance

parameters to be verified through the testing include 1) drop in chilled water

temperature across the evaporator (T, F), 2) chilled water flow rate (gpm), 3) electrical power consumption of the chiller and chilled water pump (kW), 4) chiller

efficiency (kW/ton) under full-load and part-load operation, and 5) function of the

system controls sequences.

These performance parameters will vary depending on the systems operating conditions. Although manufacturers performance data can typically be obtained for most chillers, the actual in situ performance of a chiller may vary considerably. This

performance, to be determined accurately, should be evaluated within the context of

the entire chiller system. Therefore, actual field monitoring of a chiller system in

accordance with an established monitoring protocol is often required.

A protocol for monitoring chiller-system performance has been provided in Section

3.6.2 of these Guidelines for use during the functional performance testing. The scope

of the protocol is limited to electric chiller systems, and their associated pumps and

heat-rejection equipment. The chiller-system monitoring protocol applicable to

commissioning consists of three distinct stages Stage one: development of a chiller-system monitoring plan for submittal to and approval by PG&E; Stage two:

implementation of procedures for actual field installation, placement and calibration of

chiller-system operation during he monitoring period; and Stage three: collection,

analysis and reporting of data and results. During a limited monitoring period, which

will generally last two to eight weeks but can last longer, the chiller system should

experience a wide range of operating conditions.

The commissioning fieldwork for this dynamic EEM is conducted in accordance with

the project-specific verification and functional performance test plan. This test plan

must include a clear description of the design specifications and information which

pertains to chiller controls sequence, manufacturer cut sheets and equipment

performance specifications, installation instructions and O&M manuals in addition to

the pre-startup inspection checklist, verification test checklist and the functional

performance test checklist. This information will form the basis of the commissioning

acceptance criteria and is necessary to evaluating the results of the inspections and

tests. The final commissioning test plan must incorporate all the details required to

describe the particular application and the operation of the high-efficiency packaged

air-cooled chiller system being commissioned.

In addition, a successful commissioning process will require coordination with all

commissioning team members. The responsibilities of the team members are identified

by the shaded boxes in the columns under each members title in the attached Team



Members Responsibilities chart as a means of facilitating this coordination. The attached EEM-specific Commissioning Process Flow Chart provides an overview of the

commissioning process for this energy-efficiency measure.

The pre-startup inspection of subsystems verifies, through visual examination, simple

measurements and reference to contractors reports, that the components are installed in accordance with manufacturers specifications, meet design criteria and are ready for system start-up. The pre-startup checklist addresses verification of the physical

installation, electrical system, system controls, test and balance for pumps, collection of

equipment nameplate data and documentation. In addition, related pre-startup

inspection checklists, non-compliance and corrections of components that do not meet

the acceptance criteria and inspection checklists are addressed. The checklists provided

are intended to serve as a guideline in the preparation of the project-specific pre-startup

inspection checklists. The project-specific pre-startup inspection checklists must be

finalized and approved by the CES Project Manager prior to performing any

inspections.

Following the completion of the pre-startup inspection, the verification checks and

tests can commence. They should follow the order presented in the verification test

checklist provided in this section, although the project-specific character of the testing

must be considered. The checklist provided is not intended to replace the contractors normal and accepted procedures for installing and pre-testing equipment or relieve the

contractor of the standard check-out and start-up responsibilities. The verification test

checklists should be refined, as required, with the information gathered during the pre-

startup inspections. This testing is intended to verify that all components, equipment,

systems, and interfaces between systems operate in accordance with contract

documents. The chiller, which includes the chiller soft start and restart sequences, chilled water pumping system and chiller system controls are all tested as part of this

test procedure.

Following the completion of the verification tests, the functional performance testing

can commence. This testing should follow the order presented in the functional

performance test checklist provided in this section, although the project-specific

character of the testing must be considered. The functional performance test checklist

should be refined, as required, with the information gathered during the pre-startup

inspections and verification tests. The functional performance testing is intended to

measure the energy-efficient performance of the packaged air-cooled chiller as defined

in the final design-intent document.

Prior to the verification and functional performance testing, the Prime Contractor may

need to coordinate with the building operator to modify the system control setpoints to

facilitate the operation of connected equipment for the duration of the testing. Once

stable system operation has been established, the Prime Contractor can proceed to gather

the required data. Any equipment found not to comply with the acceptance criteria must

be repaired or corrected and then retested until satisfactory results are obtained.

Following the on-site testing, the test results must be prepared, documentation compiled

and the verification and functional performance test certified in accordance with these

Guidelines. The testing procedures and results of all tests must be clearly documented in

the final commissioning report.
